I'm as far from an expert as can be, but I think if you want to use a TOM-style bridge, you will need to shim or re-route the neck pocket to accommodate the 2-3 degrees of difference a TOM bridge creates. Alligator was re-routed, I seem to recall. The other way to do it is to route a recessed channel for the TOM and sink it into the body, like Warmoth does. Without an adjustment to the neck angle, installing a TOM style bridge would give you unplayably high action. You might already know this.
